@tnulle Could you provide a version of the text which can be reviewed and annotated before this MR is merged so that we can go over the grammar, content and stylistics of the text? A PDF or OverLeaf or anything simpler than GitLab for text review.

There is an image which shows all the current text from which the grammar and style can be deduced, do you wish to change something you can annotate it in the changes of the about.html
